just out of curosity, what 3rd party ones have you tried, and what company's software is the one that sucks?
I haven't tried any third party dialers. I didn't need to. I wouldn't like to say what company it is in public. However, it's an Indian company which has (AFAIK) no branches elsewhere, so it's unlikely that you know about it. If you still want to know, I'll PM you the name of the company.

Cheers,
